11 IDUSTRIAL WARM HEATERS 1.5 WORKIG CHARACTERISTICS AD SAFET DEVICES Working characteristics Counterpressure in the combustion chamber in conformity with European standard values. Turbulation of the combustion products in the exchange pipes through stainless steel turbulators supplying a continuous and progressive action. Structure of the monoblock type heater (Mod ) including : - ventilation unit (with easy access) - thermic exchange unit (self-supporting, with easy access for periodic inspection and cleaning). Structure of the two-block type heater (Mod ) including : - ventilation unit (with easy access) - thermic exchange unit (self-supporting, with easy access for periodic inspection and cleaning). Air intake through the heater sides (for Mod also through the rear side upon request). Minimum loss of pressure relative to the air capacity when flowing through the heater; this means that there is a high available pressure for the possibile air ductings. Cover insulation made of a glass wool jacket externally covered by a galvanized sheet(sandwich type panel) in order to guarantee that the temperature difference between the external surface of the cover and the room air complies with the regulations in force. Safety and regulation thermostat devices including : - 40C fixed calibration thermostat with automatic reset. - 90C LIMIT thermostat with automatic reset C safety SICUR thermostat with manual reset. Revolving type multiple discharge heads (upon request) complete with movable fins. Filter box (upon request) made of precoated steel plate containing the extractible filtration unit and protected by a metal grill. Safety devices The device that guarantees the safety of the machine is the Safety thermostat: when it intervenes it causes the heater to shutdown completely (fan and burner) before the exiting air temperature can reach 100 C. This allows: Limiting the exiting air temperautre to values in conformity with the regulations in force. Avoiding the overheating of the exchanger and other heater parts due to system, fan or thermoregulation failures. The cause of it s intervention may be a heater malfunction: A fan malfunction A malfunction in the limit thermostat that should intervene before the safety thermostat Or a system malfunction: Increase in heat loss Decrease in the fan air capacity. Once the malfunction is removed and the heater cools down, the safety thermostat reset is done manually by pressing the reset button: Inside the electrical panel for mod Directly on the thermostat located on the outside for mod after removing the release button protection cover 18

12 IDUSTRIAL WARM HEATERS 1.4 MAUFACTURIG CHARACTERISTICS Heat exchanger entirely made of aluminized steel, resistant to high temperatures including : o Cylindrical combustion chamber with total flame return. o Flat-shape tubes with a large exchange surface. o Flue chamber with inspection for easy access cleaning. Flue turbulators made of AISI 430 stainless steel with high thermic resistance. Double suction centrifugal fans with forward inclined blades made of galvanized steel plate with dynamically balanced wheel and mounted on elastic supports. Pipe plates in aluminized steel, welded to the exchange pipes and the combustion chamber; continuous wire welding process in controlled atmosphere. Cover consisting of press-bent panels of precoated and PVC-film protected plate. Monoblock type frame supporting structure consisting of galvanized elements screwed together without welding (Mod ). Two-block type frame supporting structure; consisting of galvanized elements screwed together without welding (Mod ). Sealing gasket made of fibers in conformity with CE directives. Electrical panel built with an IP40 protection degree (IP44 for models ) containing : o main switch. o Summer-winter commutator. o Power lamp. o Working lamp. o Magneto-thermic electrical protection: Mod o Electrical protection inside motor: Mod o Fan solenoid switches: Mod o Delta-star start: Mod. 250 PLUS o Single-phase power supply 230/1/50: Mod o Triple-phase power supply 400/3/50: Mod o Upon request: triple-phase power supply 230/3/50 from model 75 to 1000 o Terminal board for connection to electrical panel 17
